基于C++的IOT网关和平台1：github项目ctGateway
初级代码游戏的专栏介绍与文章目录-CSDN博客
我的github：codetoys，所有代码都将会位于ctfc库中。已经放入库中我会指出在库中的位置。
这些代码大部分以Linux为目标但部分代码是纯C++的，可以在任何平台上使用。

这是一个开源项目，LGPL许可。github位置：https://github.com/codetoys/ctGateway.git
支持Modbus等常见协议，可以定制上报规则和语法，可以扩展协议支持。主要是经过了工厂环境考验，基本架构稳定性比较好，程序该考虑的通用问题都考虑到了。
什么意思呢，意思是各种现场BUG都遇到了，都做了预防，作为一个通用的基础架构是比较理想的。
网关程序基于C++和linux，只需要基本的linux环境，附加依赖的东西都可以自行编译，可以交叉编译为arm，整个程序包括依赖的库不到10M，可以在很小的设备上运行。CPU占用率都测过了，很低（有些设备散热不好，CPU占用率要严格控制）。
网关嘛，一般是个控制台程序，没啥好看。配套的管理工具大概是这样的（就像个专有的MQTT客户端）：
这个工具很方便，所有网关支持的指令都支持，还支持通过MQTT远程执行指令和文件传输（也就是原本用telnet和ftp实现的能力在这个网关和工具上用MQTT实现了）。大部分指令也支持批量操作。
文档是比较多的，而且还在补充中，目前的文档是这些（就是项目根目录下的index.html）：

ctGateway
introduction 介绍
The gateway program is implemented in C++,Use the UTF-8 character set.<br>
Support Modbus and transparent transmission, MQTT and MQTTS.<br>
Log files and data files are limited in size to ensure that there is no disk full failure.<br>
The data is saved instantly to ensure not lost data when power lost.<br>
The data sequence number and confirmation mechanism ensure that there is no data loss from the gateway to the platform.<br>
The storage capacity of the network is different depending on the amount of data, and the gateway supports data compression.<br>
This program has been tested in harsh production environments in large quantities，<br>
Performance, stability, reliability, and environmental adaptability have all been verified.<br>
网关程序以C++实现，使用utf-8字符集。<br>
支持Modbus和透传，支持MQTT和MQTTS。<br>
日志文件和数据文件大小受限，确保不出现磁盘满故障。<br>
数据即时存盘，确保断电不丢失。<br>
数据序号和确认机制保证网关到平台不存在数据丢失。<br>
断网存储能力取决于数据量，网关支持数据压缩。<br>
这个程序已经经过了大批量恶劣生产环境的考验。<br>
性能、稳定性、可靠性、环境适应性均经过了验证。<br>
